Texans activate Ed Reed from PUP list

The Houston Texans activated nine-time Pro Bowl safety Ed Reed from the physically unable to perform list and released 20 players, including veteran cornerback Elbert Mack, in a series of moves designed to get their roster to the NFL-mandated limit of 53 for the start of the 2013 season.

Reed, 34, signed a three-year, $15 million contract this offseason but underwent arthroscopic surgery to repair a small labral tear in his hip. Had Reed stayed on the PUP list, he would not have been able to play for the first six weeks of the season.

Mack signed with the Texans this offseason after posting 14 tackles and an interception with the Saints last season. Signed as an undrafted free agent by the Buccaneers in 2008, Mack has 103 tackles and six interceptions in 65 career games.
